ABSTRACT:
A magnetically driven apparatus useful, for instance, for conveying webs, utilizes magnetically coupled first and second rotatable elements and means for rotating one of the rotatable elements which causes the simultaneous synchronous rotation of the other rotatable element. Both first and second rotatable elements include a magnetic core, and a media bearing surface comprising a mixture of a polymeric matrix and a hard, inorganic particulate material wear and abrasion resistant layer surrounding the magnetic core. The means for rotating one of the rotatable elements includes a ferromagnetic stator member integrally associated with one of said first and second rotatable elements. The ferromagnetic stator member has a plurality of spatially separated pole teeth, wherein each of the pole teeth has an operably connected coil arranged for producing rotation of one of said first and second rotatable elements once the coil is energized.
